Specification of Letters Patent.

Application led December 17, 1908. Serial No. 467,987.

.To all 'whom t may concern.'

lle it known that I, CHARLES A. J Essor, a cltlzcn of the United States,and residing at Detroit. in the county of Wayne and State of.

Michigan, have invented a new and useful Boiler-Feeder, of which thefollowing is a specification.

My invention relates to automatic means for periodically introducing aquantity of water into a boiler, and its object is to provide a simpleand eiiieient device which shall continuously return the condensed waterof the heating system to theboiler.

n My invention consists in two receptacles, one set below the radiatorsof the heating systemand the other above the boiler, so

Aconnected that atmospheric pressure will cause the water to Howperiodically from the lower receptacle into the upper, and from theupper into the boiler.

ltfurther consists in combination with said receptacles, a series ofcontrolling valves and a-ioat,whereby the rapidity of the periodicdischarges shall be regulated.

In the .accompanying drawings F'gure '1 is a view 0f my complete device.Fig. 2 is a vertical cross section of the valve which controls theadmission of the steam to the upper receptacle. Fig. 3 is a verticalcrossvsection of the upper receptacle. vFig'. 4 is a view of lthe.retarding mechanism of the valve operating roll.` Fig. 5 is a verticalcross sec tion of an air valve. Fig. isa vertical cross section of thelower receptacle. Fig. 7 is a vertical cross section of another type ofair valve.

Similar reference charactersrefer to like parts throughout the severalviews.

In the drawings 1 is a boiler of any usual type, 2 is the upperreceptacle of my feeding systernand 3 the lower receptacle. A pipe 4connects to the boiler and to the valve 5, which connects to thevertical pipe 6 by means of a nipple 7 and T 8. Flanges 9 formY tightjoints around the pipe 6 at the ends of the receptacle 2, while holes 10permit steam to flow into the receptacle, and holes 11 pel'-l mit Waterto flow into and outl of the same.

A T 12 connects into thispipp (131 zfind froiln w ic ormst eM flow downthe pipe 6, a union 16, and acontinuation vof the pipe 6 which extendsvinto the receptacle 3 as shown Vin Flg. 6. In this receptacle 3 a bentpipe 17 having its rlower end screw 'threaded and extending through thebottom 18 of the receptacle. Jam-nuts 19 insure a tight joint. A valvebody 2() screws onto the end of this pipe 17 and receives the pipe 21thr'ough which the condensed water of the heating system enters thisfeeding device. A spring-held valve 22 normally closes the passage tothe pipe`17. A vertically movablefloat 24has a counterweight 25 of suchproportions that the weight of the. floatand the counter-weight will beabout the same as the lifting power of the float when submerged.

Vertically movable in the lower receptacle is a rod 27 which may beformed of two parts connected bya coupling 28 so that its length can beproperly adjusted. On this rod are collars 29 and 3() which are 'engagedby the float/24 as it rises and falls vand by means of which the rod 27is moved up and down. The position of the collars determines 4thedistance the float rises and falls and thereby the amount of waterlifted at each stroke. The upper end of this rod con-- nects to the'Valve stem 32 by means of the pin 33. The valve stem has a slot 34 sothat this pin may have aslight movement before it moves the valve 3Gfrom its seat in the body 5.

The operatiouof the different parts thus far described is as follows:Willi`l lmtlrrcceptacles'empty,.the float 24 will rest on the collar 30and the lower end 4of the rod 27 will -lnove the valve 22 from its seatand thus permit water to flow in through thc pipes 21 and 17 into thereceptacle 3. The pipe 17 passes up along the wall of thereceptacle sothat the flow of the water into the receptacle 3 will not disturb thefloat 24. When the oat is in its lower position it will rest on thecollar 30, and the float and the rod 27 will have moved the valve 22from its seat, the rod also holding the valve 36 from its seat, thuspermittmg steam from the boiler to enter the receptacle 2. A small Valveor pet-cock 40 may b opened to' permit the escape of any air thathappens to be in the receptacle at the ,beginning of the operations, and1s then closed. The water flowing into the receptacle 3 will finallyraise the float'24 until it contacts with a collar 29, pressing up therod 27 and permitting the valves 22 and 3G yto close.

As soon as this valve 36 is closed,` thel steam formed, and the water inthe receptacle 2 rushes up the pipe 6. The float 24 then settles as thewater escapes from the receptacle 3 and again pushes down the rod 27 bymeans of the collar 30. The valve- 36 is againiopened and steam willflow into the receptacle 2 through the holes 10 and the water in thereceptacle willflow down the pipe 6 through theholes ll. As the checkvalve l5 prevents the water from going back into the tank 3, and as thepressure in the receptacle 2 is the same as in theboiler, .the Waterfrom the tank 2 will flow into the boiler through the pipe 13. Toprevent the rod 27 from moving except under pressure of the tloat, abracket 41 may be secured to the pipe 6, which bracket has two arms 42and 43 through holes in which the rod 27 is freely movable. A spring 44between the arm 42 and collar 45 carries the weight ot the rod 27 andthe parts connected thereto'. The extensions 46 of the arm 43 carries aset screw 47 that vregulates the tension ot' thespring 4S, which has alug 49 at its free end. This lug is adapted to engage in either one ofthe circumferential grooves 50 of the sleeve 51, which is secured to therod 27. The sleeve and rod are by these means held in position untilthe'stress on the rod is suf icient to overcome the grip' of the spring.To permit the air in the receptacle 3 to escape while the receptacle isfilling and to enter while it is empty, any desirable air valve 52 maybe employed. In Fig. 5 is shown a valve consisting of a body formed bytwo parts 53 and 54 secured together, into which the pipe 55 may bescrewed, which pipe'connects the valve to `the receptacle `3. A lighttube 56 connects to the float 57 and is formed with holes 58. So longas; air alone passes through the pipe 55 the parts will remain intheposition shown in Fig. 5'and the air will pass into the valve throughthe holes 58 and out through the top'of the tube\56. As soon as anyWater enters, the float will `rise and the rubber washer 59 will closethe passage around the tube 56 thus sealing the passage.

Another type of air valve is shown in Fig. 7 which is the usual swingcheck valve 69 with a small hole 70 in the valve disk 71. This permitsair'or steam to slowly pass from the lower receptacle through the pipe72, valve 69 and pipe 7 3 to the sewer; while opening and permitting arush of air into the receptacle 3 when the vacuum in the receptacle 2causes thewater to flow up the pipe 6. Any water that may pass throughthe hole will flow to the sewer. 'Normally a tank 60 should beinterposed between the receptacle 3 and thereturn pipe `61 of thesystem, but thistank 60 is not absolutely necessary with pressuresystems. `Where a pressure system is employed, that is, where thepressure of steam is above that of the atniospliere,'the air valve willbe used, but with a vacuum system, where the pressure of'tlie steam isthan that of the atmosphere, the air valve cannot be used. In that casea small pipe 63 should be used to connect the top of the receptacle 3with the top of.

the tank 60. This pipe 63 can also be used with the pressure system.Under the usual arrangements of boilers and radiators it is necessarythat the boiler be placed at a lower level than the radiators so thatthe condensed water can return to the boiler by gravity. rlhis commonlynecessitates the radiators in basements to be secured to the ceilingswhich or" course is very undesirable. But with this system justdescribed the boiler can be placed at any desirable location, all thatis necessary being that the receptacle 3 be so far below the radiatorsthat the condensed water will flow thereto by gravity, and that thereceptacle 2 be so far above the boiler that the water will flow to theboiler. Under all except the most unusual conditions, the distancesbetween the two receptacles need not be above ten feet.
